Locations and Measurements

The Indiana State Climate Office maintains weather stations across the state (right) where real-time measurements are reported in 5-minute, 30-minute, hourly, daily, and monthly temporal intervals.

Measured variables include:

• Air temperature 0.5, 1.5, 2, and 3 meters (1.6, 4.9, 6.6, and 9.8 feet)
• Soil temperature and moisture depths of 5, 10, 20, and 40 centimeters (2, 4, 8, and 20 inches)
• Solar radiation
• Relative humidity
• Precipitation
• Wind speed and direction 3 meters (9.8 feet)
